Definitions

  • the invention concerns a deodorant, consisting of a water emulsion of a perfume oil, and of a certain quantity of microcapsules, filled with the same perfume oil, and mixed with the water emulsion of the perfume.
  • the invention also concerns the method of preparation of the deodorant.
  • deodorants in which the perfume is mixed with other components in order to obtain a gel as well as deodorants made by plastic materials of various types.
  • liquid deodorants which can be sprayed directly in the air or deodorants which release perfume through a porous surface, or else deodorants in granular form.
  • deodorants with the exception of the liquids sprayed in the air, are capable of a slow, continuous release of perfume, once they are put in use for a certain period of time.
  • instantaneous deodorants consisting of a liquid formula which is finely sprayed in the room to be deodorized.
  • deodorants are sprayed either by means of a manual pump or, in the well-known aerosol form, by a compressed or liquified propellant gas.
  • liquid deodorants are generally hydroalcoholic formulae, so that the sprayed product is effective for a limited length of time, depending on the volatility of the components of the formula and of the perfume itself. This time is always rather short, especially taking into account the fact that the products rapidly tend to deposit on the ground by gravity.
  • WO-A-92 00 722 relates to a fragrance composition comprising a fragrant base in the microencapsulated form. This composition is specifically provided for topic use.
  • the present invention proposes a deodorant composed of a liquid phase constitued by a water emulsion of a perfume oil and a phase constitued by microcapsules containing the same perfume oil.
  • the invention also concerns the relevant method of preparation.
  • the deodorant provides the advantage of a longer-lasting effect, as compared to the normal deodorants, as, beside the immediate release of perfume at the moment of its dispersion in the environment, a further effect is provided, owing to the release of perfume from the microcapsules, when, once deposited on various surfaces, they get broken when walking on them, or by other means.
  • the scope of the invention is that of providing a deodorant which overcomes the limitations of the usual deodorants by immediately perfuming the air when sprayed, and then by mantaining for a relatively long time its capacity to release perfume.
  • the invention provides a deodorant composed of a liquid phase, constitued by a water emulsion of perfume oil, and of a certain amount of microcapsules of the same perfume oil which are sprayed in the air mixed with the rest of the product, and which then tend to fall down by gravity.
  • the water emulsion phase of the deodorant serves the purpose of immediately perfuming the air, while the microcapsules provide a longer-lasting action as they release their perfume when they are mechanically broken as they are walked on or by other means.
  • the deodorant is constituted by a water emulsion of a perfume oil, to which a certain quantity of microencapsulated perfume has been added and held in suspension within the perfume emulsion in water.
  • a formula suitable for the purpose of the invention is as follows: Preferred Composition Perfume 0.5% - 10% 3% Emulsifier 0.2% - 10% 2% Microencapsulated Perfume 0.2% - 10% 2% Preservative As needed Demineralized Water Balance to 100%
  • This perfume will have to be chosen among those which are non-miscible with water.
  • perfumes which more or less spontaneously become emulsified in water must be excluded.
  • Such characteristic is mandatory because only non-emulsifible perfumes are suitable to be microencapsulated according to the usual techniques.
  • the normally used emulsifiers which are useful to disperse perfumes in water can be used for the purpose of the present invention.
  • This emulsion is usually a milky-white liquid, or in rarer rases, an opalescent liquid.
  • emulsifier capable of providing a stable emulsion for a period of at least six months at room temperature.
  • the preservative used must guarantee an effective protection of the product against a wide range of bacterial strains and yeasts.
  • Kathon CG® produced by Sandoz, used at very low levels, between 3ppm and 10ppm, preferably 5ppm.
  • microcapsules containing the perfume are constitued by the perfume itself, finely dispersed in microscopic droplets coated by gelatine.
  • microencapsulation process is not described as it can be carried out through known techniques.
  • microcapsules of perfume and gelatine contain between 50% and 90% perfume, preferably between 80% and 85% perfume, and have sizes ranging from 1 to 10 micron, preferably 5 micron.
  • microcapsules are used under the form of a water suspension ("slurry"), containing between 10% and 30% microcapsules, preferably 20%.
  • microcapsules in suspension in water tend to sediment it is necessary to keep them under moderate agitation during the preparation of the finished product.
  • the finished product is prepared as follows:
  • the deodorant product according to the present invention provides, as stated above, the dual advantage of an immediate deodorant/perfuming action and of a further continuous release of perfume, thanks to mechanical break-up of the microcapsules when they were walked on, etc.
  • a further advantage is due to the fact that the product does not contain solvents, thus overcoming possible risks of flammability and other possible drawbacks related to the use of solvents.
